2.1 技术简介

技术定义:

Mobile vegetable cultivation system for urban areas with "baker boxes" as main elements.

2.2 技术的详细说明

说明:

The main technology applied in the urban gardening project "Princess gardens" can be described as mobile vegetable culitivation system based on the use of "baker boxes".
"Baker boxes" are plastic boxes (size: average area of 40 cm x 60 cm x 35 cm) made out of heat-resistant materials, which do not contain softeners. The bottom part as well as the side parts are formed in a grid pattern (holes of 1cm³ size).
For the vegetable production, cultivation units ("box towers" ) are built out of two boxes by placing them on top of each other. The lower box is filled with organic material (composition of the material like in a compost) and the upper box is filled with garden mould (or other earth material suitable for cultivation). To prevent the washing out of earth material through the grid pattern, carton is put on the bottom as well as on the side walls of the upper box.
During a period of time (length can vary from 1 to 3 years) the upper box can be cultivated according to the principles of "good practise" (e.g. crop rotation). During this time, the lower box serves as compost. In the course of each year this box is checked if the ongoing decomposition processes have lead to the creation of free space in the box. In this case, organic material needs to be refilled.
In the end of the 1-3 years-cultivation period the upper box is emptied and the contained earth material can be used for purposes such as landscaping. The box is then filled with organic material and switched with the lower box, which should contain "ready to cultivate"-compost material. The cultivation can then be restarted.

Purpose of the Technology: The purpose of the technology is to allow cultivation on sealed or contaminated soils. Through the use of the box towers as cultivation units the roots of the plants never get in touch with the soil. While the main rooting zone is to be found in the upper box, deeper rooting plants can grow down to 70 cm into the lower box without reaching the soil in place.
Another purpose of the technology is to create a mobile cultivation system. If needed, the boxes can be easily moved away even during the vegeation period.
Last but not least, the technology has the purpose to create a space, where knowledge sharing on a practical basis regarding the topics e.g. agriculture, sustainability and health can take place.

Establishment / maintenance activities and inputs: For the establishment of the technology first and foremost a sufficient number (depending on the size of the gardening area) of "baker boxes" is needed.
Maintenance activities consist of refilling the lower box with organic material.
This is also true for the required inputs.

Natural / human environment: The environment is strongly influenced by humans, as the first urban structures in this area already were established about 200 years ago. Regarding the topic soil this led to the conversion of the natural soils in place to Technosols.

3.2 应用该技术的当前土地利用类型

注释:

Major land use problems (compiler’s opinion): The major land use problem can be addressed as a lack of cultivation plots within the urban areas. This is due to the fact that the soils are to a great extent sealed or contaminated.
As a result in the urban area there is also a lack of pratical learning areas which relate to the topics agriculture and soils.

Major land use problems (land users’ perception): As major land use problems the cultivation circumstances are regarded. This inculdes the topics of destroyed natural soil fertility and a lack of water infiltration into the ground.

6.4 成本效益分析

注释:

An economic analysis is hard to make, as the main goal of the project is not economical profit. In the interviews it was stated, that each year about 50.000 people visit the garden. To have an outreach to such a high number of people with a budget of about 500.000 € is regarded as "benefical" by the project members.
Only looking at the financing part it was stated in the interview that the garden is one of the very few urban gardening projects that can provide for its recurrent costs itself.

6.8 技术的弱点/缺点/风险及其克服方法

土地使用者认为的弱点/缺点/风险	如何克服它们？
limited productivity
are highly dependent on irrigation, as the boxes dry-out fast (high evaporation/ surface area)
Soil can be easily lost/washed out throught the grid pattern (especially in the long term, when the erosion measures are reduced (decomposition of carton)
The spacing in between the boxes serves as habitat for snails.
The carton sometimes rots away in the course of the cultivation period. This leads to a loss of soil material out of the boxes.

编制者或其他关键资源人员认为的弱点/缺点/风险	如何克服它们？
dependent on a high supply of "baker boxes"
dependent on external inputs (especially organic material)
allows only for hand labour
